WILLIAM R. BELL, OF VENETIA, PENNSYLVANIA,

ANTIREFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application led January 30, 1907. Serial No. 854,795.

To all whom it may concern:

Be it known that I, WILLIAM R. BELL, a citizen of the United States oi America, residing at Venetia, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Antireillable Bottles, oi which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to anti-refillable bottles, and the invention has for its object to provide a bottle with positive and reliable means for preventing the refilling of a bottle without detection. 'Io this end, I have devised a novel cap adapted to Iit upon the neck of a bottle, said cap being equipped with interlocking means for engaging the neck and preventing the cap from being removed, except by breaking the same. In consequence of such a construction, it will be impossible for the bottle to be used for fraudulent purposes by surreptitiously refilling the same. It will thus be seen that I aim to eliminate the nefarious practice oi using the bottles of well known brands of liquid and refilling the same with an inferior article.

The detail construction entering into my invention will be hereinafter more fully described and then specifically pointed out in the appended claims, and referring to the drawing forming part of this specification, like numerals of reference designate corresponding parts throughout the several views, in which:

Figure I is an elevation of a portion of a bottle constructed in accordance withmy invention, Fig. 2 is a vertical sectional view of the same, Fig. 3 is a horizontal sectional view taken on the line xwa of Fig. 2 illustrating the cap locked upon the neck of a bottle, Fig. 4 is a similar view illustrating the cap loosely mounted on the neck of the bottle, and Fig. 5 is a perspective view of the upper end of a bottle neck constructed in accordance with my invention.

To put my invention into practice, I use an ordinary bottle l and provide the upper end of the neck thereof with threads 3 and a vertically disposed shoul der 4. Adapted to screw upon the threaded end of the neck 2 is a cap 5 having an annular compartment 6 formed in its upper end above the threads 7 of said cap. When forming or molding. the cap 5, I embed one end of a curved spring 8 in said cap, the end 9 of said spring protruding into the annular compartment 6 to engage the shoulder 4 of the bottle neck 2 when said cap is locked upon said neck.

In Fig. 4 of the drawing, I have illustrated the cap as loosely mounted upon the bottle neck 2 and it will be observed that when the cap is further rotated that the end 9 of the spring 8 will engage in the shoulder 4 of the bottle neck 2 and prevent the cap 5 from being unscrewed. In order that the cap can be placed in engagement with the bottle neck 2 and the spring 8 held under tension as illustrated in Fig. 4 of the drawing, I bevel the upper end ofthe neck 2 as at l0 whereby when the cap is rotated the spring will ride over the upper edges of the bottle neck 2 and remain under tension until it enga-ges in the shoulder' 4.

To seal the bottle prior to placing the cap 5 upon the neck 2, I use an ordinary cork or stopper ll which can be easily removed after the cap 5 is broken.

The cap 5 is preferably constructed of vitreous material similar to the bottle l, although it is obvious that other materials can be readily used.

I do not care to confine myself to the type of bottle in connection with which my invention is used, or to such variations in the details of construction as are consistent with the appended claims.

What I claim and desire to secure by Letters Patent, is

The combination with a bottle neck threaded exteriorly adjacent its upperl end and having the rim of the upper end beveled, and having a vertical notch extending from the lower edge of the beveled portion to the uppermost thread, of a cap threaded interiorly to engage the threads of the bottle neck and having an 4annular interior recess above the threads, and a curved spring partially embedded in the cap and partially lying within said annular recess of the cap with its free end adapted to engage in said notch.

In testimony whereof I afhx my signature in the presence ot' two witnesses.

WILLIAM R. BELL.
